Since commit 4b563a066611 ("ARM: imx: Remove imx21 support"), the config DEBUG_IMX21_IMX27_UART is really only debug support for IMX27.

So, rename this option to DEBUG_IMX27_UART and adjust dependencies in Kconfig and rename the definitions to IMX27 as further clean-up.

This issue was discovered with ./scripts/checkkconfigsymbols.py, which reported that DEBUG_IMX21_IMX27_UART depends on the non-existing config SOC_IMX21.

This is unsuitable for 4.19, as CONFIG_SOC_IMX21 is still present there. It is probably okay for 5.10. I did not check others.

Good point, I will drop this from 5.4 and older now.

thanks,
